Title: Method of and apparatus for testing a lip seal
IPC: G01M13/00
Filed: 1962-08-03
Abstract: 936,823. Testing lip seal rings. GENERAL MOTORS CORPORATION. Aug. 3, 1962 [Aug. 25, 1961], No. 29906/62. Class 122 (5). A lip seal 28 is tested prior to use by rotating it with its lip 30 in contact with a test shaft 67 and obtaining an indication of the magnitude of friction generated between the lip and the shaft for a given speed. The magnitude of friction may be indicated by measuring either the temperature produced or the torque transmitted by the friction generated and in the apparatus shown both these means are used. The seal 28 is press-fitted in a holder 22 connected by a shaft 20 to a dynamometer 18 driven by an electric motor (not shown) and rotatably supported on uprights 14, 16. The hollow test shaft 67 is secured to a disc 68 connected to a housing 54 concentrically mounted on ball bearings 56 and 58 in a housing 36 connected to sleeves 42, 44 that are interconnected by a plate 45 and adjustably slidable on horizontal bars 46 and 48. A clamp 62 of a strain gauge is secured to an extension shaft 60 of the housing 54 and a beam 64 carrying strain elements 65 is secured to the plate 45 by a bracket 66. The temperature at the surface of the test shaft 67 can be measured by thermocouples 70. Compressed air can be supplied from a system 74 including a pressure regulator 76, gauge 78 and flow meter 80 to the holder 22 which can also be supplied with oil by a system including an inlet pipe 88, a return pipe 92 and a pump 86 and heat exchanger 84. To test a seal 28, the seal is initially inserted in the holder 22 in the reverse position to that shown in order to determine, by observing the air pressure at which a predetermined rate of air flow occurs, the pressures required to keep the lip 30 in contact with the shaft at different speeds since centrifugal force tends to urge the lip outwardly. The seal is then inserted in the position shown with the lip in contact with one of the thermocouples 70 and the holder rotated at varying speeds. Sufficient oil is circulated to cover the seal and compressed air is supplied at the predetermined pressure to correct for the centrifugal effect on the lip pressure. At the desired speed the shaft temperature is measured by the thermocouples 70 and the angular deflection of the shaft is sensed by the strain gauge 62 and used to operate a torque recorder.

Title: Improvements in and relating to windings of alternating current dynamo electric machines
IPC: H02K3/28
Filed: 1919-12-02
Abstract: 164,046. British Thomson - Houston Co., Ltd., Clough, F. H., and Taylor, H. W. Dec. 2, 1919. Coils and conductors; windings. - Consists in methods of transposing the winding components for eliminating eddy - current losses in multi-turn alternating - current armature windings in which the conductor is divided into sections numerically equal to the number of turns in the winding, which sections are subdivided into subsections, both sections and subsections being in parallel and mutually insulated throughout the winding. The Specification gives an analysis of the eddy-producing fluxes across the slot into two components, viz. elements of variable density across the depth of each conductor due to its own current, and elements of constant density across the depth of any conductor due to the aggregate slot current below it, and it is shown that the methods of transposition of the sections and subsections illustrated give a zero resultant of eddyproducing flux. Fig. 4 shows a winding with an even number of coils per phase, the conductor being made of four sections each comprising three subsections, of which one group A, B, C is shown in heavy lines throughout the winding. The actual arrangement of this group in successive positions 1, 2 - - 8 in the slots is shown in Fig. 3. In half of the positions occupied by any section, e.g. 1, 4, 5, and 8, the order of the subsections is reversed in comparison with the other half 2, 3, 6, and 7, the result being that equal numbers of constant flux elements link the subsections of the winding in opposite directions. In Fig. 7 a winding is shown with an uneven number of coils per phase in which the subsections in a. section are reversed in passing from one side of a coil to the other. It is shown that in this form the number of variable flux elements remaining unoppcsed is twice the number of oppositely directed and uneliminated constant flux elements, the result being the elimination of eddy currents due to the constant fluxes. In the form shown in Fig. 10, the number of subsections in the section equals the number of sections in the conductor, and the position of the subsections in the section is transpcsed from coil to coil in the same manner as that of the sections in the conductor. Thus, in the top position 8 of the section A, B, C, D in the slot, the subsection A is at the top, and when the section is at the second position 7 from the top of the slot the subsection A is second in the section, and so on. In larger machines the subsections may be divided further into componeuts which are transposed within the subsections which, together with the sections, are transposed within the coils by any of the methods described above, and this process may be continued until the desired elimination of eddy currents is obtained. Specification 10919/13 is referred to.

Title: Processes for coating ferrous metal with copper
Inventor: JENKINS HERBERT ARTHUR HENRY
IPC: C23C18/38
Filed: 1961-08-21
Abstract: Ferrous metals are coated with copper by chemical replacement when treated with an acid solution of a copper salt; and iron that enters the solution from the treated surfaces is replaced by copper by continuously or periodically bleeding-off part of the solution and passing it through an acid-resistant cation exchange material having exchangeable copper ions.  The iron content of the solution is maintained below 30 grams of ferrous iron per litre and to attain substantially constant coating weight the ferrous iron content is not allowed to vary by more than 3 grams per litre.  As coating continues there is loss of acidity of the solution and the iron-exchange material also has exchangeable hydrogen ions to rectify the drop in acidity.  The solution is free from sodium or other metal ions except copper (and the dissolved iron) and activating chloride ion is introduced in the form of hydrochloric acid.  A modifying agent is present in the solution and preferably this is an ethylene oxide condensate of a long-chain aliphatic amine. The cation exchange material may be sulphonated cross-linked polystyrene resin charged with copper and hydrogen ions and when exhausted it may be regenerated by successive treatments with sulphuric acid and copper sulphate.  The initial composition of the coating solution is CuSO4.5H2O 200 g/l., condensate 5 g/l., HCl acid (35% HCl) 120 g/l. Specification 927,576 is referred to.
